1. Review of Cell Cycle I play music at the club

2. Name the 3 Parts of the Cell cycle 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis: copies its DNA in preparation for cell division Gap 2: Cell prepares for division of the nucleus 2) Nuclear division: Mitosis 3) Cytokinesis

3. Name and describe the 4 phases of mitosis ( in order) Prophase: Nuclear membrane breaks down Nucleolus disappears Chromosomes coil and thicken Spindle begins to form between the centrioles

4. Metaphase: Chromosomes attach to the spindle and align along the equator of the cell. Anaphase Microtubules shorten, moving chromosomes to opposite poles.

5. Telophase: Chromosomes reach poles of cell Nuclear envelope re-forms Nucleolus reappears Chromosomes decondense

6. What is a sister chromatid? Sister chromatids are structures that contain identical copies of DNA and are attached together with a centromere

7. What is cytokinesis? Cytokinesis: a process that divides the cytoplasm which results in two cells, each with identical nuclei.

8. Centromere: joins the two sister chromatid Spindle: The apparatus that moves and organizes the chromosomes before cell division. Chromosome: A single copy of DNA Chromatin: All the chromosomes in a relaxed state (during interphase) Sister chromatids: two copies of DNA

9. Cancer Cancer is uncontrolled cell division
